Ronaldo still a doubt but Bale shakes off flu ahead of Bayern

Real Madrid coach Carlo Ancelotti says Cristiano Ronaldo may only be fit enough to be a substitute for Wednesday's Champions League semi-final first leg against Bayern Munich.

Ronaldo has not played since limping out of Madrid's quarter-final first leg against Borussia Dortmund on April 2, missing his team's last four games [including last week's 2-1 Copa del Rey final win over Barcelona] with a mixture of knee and thigh problems.

The Portugal captain has trained for two days with his team-mates, but might not yet be ready to start such a huge game, Ancelotti revealed.

Moyes lasted just 348 days at United - compared the the 27 years his predecessor Sir Alex Ferguson spent at Old Trafford - having overseen the club's slump from being champions last year to currently occupying seventh place this season.

"Cristiano trained normally today, he has trained well these last days," Ancelotti said. "Tomorrow we will have another test to be sure. He wants to play and we are confident, but the decision will be made tomorrow. If there is a risk he will not play."

Ancelotti would not comment on reported differences of opinion between Madrid's medical team and the player's camp, but did stress that he did not want to risk any further setback which could rule Ronaldo out of next week's second leg in Munich.

"Cristiano has been injured and undergone treatment," Ancelotti said. "He has consulted with the club's doctors, has done his recovery work, and has been training for three days, two last days with the group normally. He feels good, we feel good, tomorrow we will do a physical test and if he feels good he will play.

"The tie will not be decided [in the first leg], maybe we will get an advantage, but it will be decided next Tuesday. We must also think whether Cristiano on the bench could give us more options. Any minute could be the decisive minute."

Last week's Copa del Rey final match-winner Gareth Bale missed training on Monday with flu, but was back taking a full part on Tuesday morning.

"[Bale] had a small problem yesterday, but today he is fine," Ancelotti said. "The goal he scored against Barcelona, in a final, it is normal that it will give him more confidence.

"He had some problems at the start, but not anymore. He has scored a lot of goals, and played for the team. He is going to improve even more next season as he is training with us and has the good luck of not playing the World Cup."

Although Brazilian left-back Marcelo is back fit after a month out with a hamstring injury, Ancelotti confirmed that Fabio Coentrao would keep his place in the XI. Sergio Ramos is expected to play in central defence despite a niggling neck-muscle injury, while Isco is most likely to drop out should Ronaldo start.

Ancelotti said he expected the Bayern game to take a similar pattern to that Copa final, given current Munich coach Pep Guardiola's Camp Nou past.

"We played against Barcelona with 11 players, very solid and helping each other," Ancelotti said. "Tomorrow will be the same. We will need a lot of good defensive work, and to control the play to show our own quality.

"The philosophy that Guardiola has put in is more or less the same [as at Barca], obviously with different players but also of good quality. But I do not believe the coaches will decide this semifinal, the players will do that."
